En man bland många kvinnor : en studie om varför män väljer läraryrket i den tidiga grundskolan
The english name of this essay is ?One man among many women?. This essay takes its starting point in the situation today with few male teachers in the earlier years of elementary school. I have decided to look at the small group of males that actually started the education to become teachers and why they did it when the profession as teacher today is low-paid, low status and is a profession with a large dominance of female teachers. I have chosen to write about this because of the importance for the children to meet both men and women as teachers in the early schoolyears.
Syntes och egenskapskarakterisering av volframoxid framställd med magnetronsputtring
The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.
Reglering av matarsystem vid höghastighetskapning
Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.
Glödskalsrensning på göt med varierande tvärsnitt
På Ovako i Hofors, framställs stål via götgjutning. Göten har ett kvadratiskt tvärsnitt som varierar mellan 300 och 700 mm. Dessa transporteras från stålverket, till valsverket för uppvärmning. Varpå de varmvalsas till färdiga ämnen. Under tiden i ugnen när göten värms upp, oxiderar järn och andra legeringar och bildar glödskal.
Svensk kod för bolagsstyrnings påverkan på aktiekursen i företag med frivillig tillämpning
Due to a rising debate concerning corporate governance that has caused increasing demands for companies? transparency, several codes of conduct have been introduced. The Swedish Code for Corporate Governance is obliged to companies with a turnover exceeding three billions. There are companies that voluntarily apply the Swedish Code. Possible causes to this phenomenon ought to be that the code for corporate governance conveys legitimacy through the insight into the affairs of a company the public receives, through the report of the corporate governance that is published in the annual report and on the home page of the company.
Revisorernas oberoende ifrågasätts : går det att sitta på dubbla stolar, få dubbla inkomster och ändå bevara oberoendet?
The recent accounting scandals in large companies in both USA and Europe, such as Enron and Scandia, have led to a huge debate about the quality of financial reports approved by auditors who, at the same time, offer consultancy service to their audit clients. Many researchers and experts argued that there is a role conflict when an auditor offers consultancy service to audit clients. They argue that the main duty of an auditor is to verify the truthfulness of the company's financial statements. Giving consultancy service to the audit clients will impair the auditor's role to examine the company's books independently because of the economic bond between auditors and audit clients.As a result of the Enron scandal, the legislators in the USA have made restrictions to how auditors provide non-audit service to audit clients. However, the legislators in Sweden, unlike the US, did not choose to introduce such restrictions.
Organisationsplan för Skanska Direkt Värmland
AbstractSkanska Sweden has decided to split the organization that earlier handled both large and small projects into two different subsidiaries. A consequence of this is that all construction service handling will from now on be enforced under the name Skanska Direkt AB. The management of Skanska sees this as an opportunity to develop the organization and in the long term achieve higher earnings. The task which Skanska in connection with the reorganization wanted to be investigated was a proposal on how the organization of work with the insurance work in the future should look like.The organization that is handled is from production manager to professional workers and includes damage handling that has been obtained from insurance companies in the southern and northern parts of Värmland. The purpose with this work is to present a different kind of view to the problem with developing this branch of the company. The main target was to work out a proposal of an organizational plan for the damage handling in Skanska Direkt AB that is possible to apply, less sensitive for dismissals, results in higher earnings, obtains higher customer satisfaction and also a staff stab that develops their skills at their own.The report and work progressed as following:Opening theory study of strategies to obtain the objectives set.Restructuring of existing organization with theories as support.Interviews with the actors involved to verify feasibility of the developed organization plan Organization chart, the result of work means that some workers at each location shall be responsible for a small group of workers and work independently. They shall manage the process of invoicing and calculate costs at the same time as they work out on the workplace.

Results of the study show that there is a anatla different ways to go, but some are more common than others..
Value at Risk : En jämförelse mellan VaR-metoder
Bakgrund: I och med att Basel II har instiftats i Sverige så måste finansiella institutioner beräkna sin marknadsrisk på sina portföljer. Detta kan göras genom olika VaR metoder. Dessa ger dock olika uppskattningar på marknadsrisken. De finansiella instituten får använda sig av den metod som de anser reflektera marknadsrisken bäst. Det finns dock ingen metod som utsetts till standard.Syfte: Syftet med detta arbete är att jämföra olika VaR-metoders skattning av marknadsrisken utifrån verkligt utfall, för att urskilja vilken metod som är funktionsdugligast.Avgränsningar: Denna undersökning inkluderar fyra olika VaR metoder.
The existence of low balling on the Swedish audit market -A study of companies listed on the NASDAQ OMX Stockholm that voluntarily changed audit firm 2002-2010
Background and Problem: The lack of auditor independence is discussed being oneof the reasons to scandals such as Enron and HQ. A pricing strategy that has beendebated impairing auditor independence is low balling. To win a new client in atender process, audit firms supposedly offer an audit fee below cost and then increasethe fee the following years to recover the initial loss. The auditors? future financialinterest in the company due to the initial loss is by some believed to impair auditorindependence, which makes low balling in Sweden a relevant phenomenon to study.Aim of study: This thesis aims to explain if low balling exists on the Swedish auditmarket and if the size of companies affects the results of low balling.Methodology: To achieve the purpose of this thesis, a statistical study wasconducted.
Working Caital Policy : Ett sätt att driva verksamheten
The working capital describes the short-term financial position and focus on cash flow and the actual inflow and outflow of money in the company. Working capital is part of the company's financing and consists of the company's current assets and current liabilities. There are resources that are used in the daily activity and can be optimized. The more effective they are in circulation, the higher value they create. The control of working capital is called Working Capital Management and has its basis in the company?s Working Capital Policy.
Vad händer när två blir en? En kvantitativ innehållsanalys av konsekvenser för lokaljournalistiken efter tidningsfusionen i Karlskoga.
Authors: Elina Haimi, Emelie Nordh, Kattis Sundén Title: What happens when two becomes one?Level: Bachelor of Journalism Location: University of Gothenburg Language: Swedish Number of pages: 50A simple rule that any handbook in journalism will tell you is that it?s better, if not necessary, to have at least two different sources, rather than one, when you tell a story. This will keep information accurate and non-biased. You will get closer to the truth if you hear more people. We started to wonder if this would be the case with news papers as well.
Avledning av öringsmolt (Salmo trutta) från turbinintag
Vattenkraftstationer, med dammar och turbiner, utgör hinder för nedströmsvandrande smolt. Syftet med denna studie var att undersöka turbindödligheten för öringsmolt (Salmo trutta) vid två kraftstationer, de befintliga ytlänsarnas avledningseffekt och om effekten kunde förstärkas genom mörkläggning i form av övertäckning av kraftkanalen med en presenning vid turbinintaget. Utöver detta var avsikten även att undersöka om det fanns något samband mellan smoltgrad och smoltens förmåga att förflytta sig mot havet. I Emån i Småland fångades 46 öringsmolt som radiomärktes och sattes ut vid två kraftstationer och pejlades dagligen i sex veckor. Det var en större dödlighet vid den övre stationen än vid den nedre.
Inverkan av torrsubstanshalt och temperatur på kompostens syrabildning :
Composting is a process in which organic matter is mineralized by microorganisms. In January 2005 landfilling of organic waste was prohibited in Sweden. With this prohibition composting has become an important alternative to handle the produced organic wastes. One problem with continuous small-scale composting is the production of organic acids that will inhibit a further composting process. The aim of these theses was to study what effects temperature and dry matter content had on the production of organics acids, and what effect the organic acids had on the mineralisation of the substrate as well as the stability during storage of the product.
Nu kör vi! Serieentreprenörernas framgångsrecept
Bakgrund och problem: I och med finanskriserna har intresset ökat för företagens utlämning av upplysningar kring risker och osäkerhetsfaktorer. Variationen av mängden av risker samt utförligheten i hur dessa beskrivs kan skiljas mycket åt, då de företag som följer ÅRL vid sidan av IFRS måste redovisa sina väsentliga risker och osäkerhetsfaktorer. Företag, som enbart följer IFRS, har inte detta krav och har därmed möjlighet att inte redovisa vissa risker.Syfte: Syftet med uppsatsen är att få en inblick i hur företagen upplyser om sina risker och osäkerhetsfaktorer och vilka och hur många risker och osäkerheter som man upplyser om. Detta för att få en bredare syn på vad företagen anser att dessa termer betyder, vad som ingår i dem och hur företag generellt kommunicerar ut sin riskrapportering.Avgränsningar: I denna studie analysera företag noterade på Stockholmsbörsens Large, Mid och Small Cap-listor, som har publicerat en årsredovisning för 2009 samt halvårsrapporter från 2010.Metod: Genom en kvantitativ innehållsanalys undersöktes 122 börsnoterade företags årsredovisningar och halvårsrapporter från 2009 ? 2010.
